Specification of Letters Patent.

Patented .nine 1e, 1914.

Application led June 12, 1913. lScr'iall'o. 773,321.

To all whom it may concern Be it known that I, RICHARD NEwsAM, citizenof the United States, residing at peoria I-Ieights, in the county ofPeoria and State of Illinois, have invented certain new and usefulImprovements in Door-Checks; and I do hereby declare that the followingis a full, clear, and exact description of the invention, which willenable others skilled in the art to which it appertains toma-ke and usethe same.

This invention relates to a door check or holder. It relates moreparticularly however to a new structure in a door holder or check ofthat type employing a spring held member to lie in the path of and to beengaged by a kee er carried by the door rEhe object of t einvention isto provide a very simple form of door check or holder of a single partwhich will require no machine work, or the work of an experiencedmechanic; merely the assembling of the various parts necessarilyentering into such a structure.

Another object is the provision of a device of this character having Vanopening or window in its side through which the parts entering into itsstructure can be introduced so that the device may be assembled in a fewmoments time.

To the end that the invention may be understood I have provided theaccompanying drawing, in which,

Figure l shows the complete device in perspective. Fig. 2 is atransverse section of the same in elevation. Fig. 3 is a side elevationVin part section showing a portion of a door and a keeper associatedwith it.

rIhe device of my invention consists of a single casting comprising abase portion A provided with suitable screw holes B for securing it tothe floor, and C is a vertical extensionv vpreferably tapered toward itsupp'r'end merely to present a pleasing ap pearance, there being includedat. the rear of the extension a strengthenin n D. -.\'I`he extension Cis hollow, eing cored out-at E, and adapted to receive the partswhiclrare employed to holdthe door. In the side'ot' the extension is anopening or window F. G is an opening in the top of the extension C and'H is a ball or other similar or suitable member provided with a roundedupper surface which is entered through the window F to seat in saidopening Gr, the said opening being somewhat smaller alanine Wholediameter. 0f the han so that the metal surrounding the said openingconstitutes a flange G1 forming said seat.

J is a spring adaptedto bear upwardly against the ball to hold it inplace, the lower end of said spring resting upon the base A as clearlyshown in Fig. 2. i The window is suiiiciently wide to admit the ball andsaid spring and preferably there is a depending lip K left above thewindow as a part o the casting to prevent `lateral displacement of thespring, there also bein preferably a portion L of the partC 'be ow thewindow to prevent lateral displacement of the lower end of the spring.That is to say, should there be any tendency of the spring to sliplaterally it might do so if the window ext-ended entirely to the top andbottom but the portions K L of the casting will prevent this.

In constructing a door stop it is important that the structure should beof very low cost both as to itsmanufacture and the work required inassembling it. The devices of which I am aware have usually consisted ofmore than one part which must be as sembled and secured before thespring and other parts are put in place and then riveted or otherwisesecured to one another. This, of course, means expense and a resultinggreater cost than one that may consist ofbut a single part or casting.as herein re qulring no machine work or the expert work4 of-a mechanic.

From the fact that the bodfy of my door check or door stop is made o andrequires but one piece which can be a simple casting,

it differs. from any device of this type of which I am aware.

In assembling the device the spring J being necessarily a strong one, bymeans 'of a suitable tool such as a pair of suitably constructedpincers,for example, can be compressed after the ball has beenintroduced and placed in its seat through the window and when introducedis permitted to expand to engage the ball and rest upon the base A. Theact ofassemblingthus requires but a moment, the device being completeand ready for use.

M indicates a door and N a Vkeeper secured thereto in any suitablemanner and provided with fan upturned point O to engage and depress theball and having a socket P to receive the latter. When the keeper ismoved against the ball the point engages and depresses it, the lat-terspringing up into the socket P holding the door securely.

Having -thus described my invention what I desire to secure by LettersPatent is:

l. A door holder including in its construction a body of a single partadapted to be secured to a support and provided With an internal boreclosed at one end and open at the other,'the bore being reduced in diameter at its open end, there being an opening in the side of the membercommunicating with the bore, a member seated upon the part Within thebore at the said open end of the latter and projecting outside the saidpart in position to be engaged by the door, and a spring seated in thebore and bearing upon the member and holding it elastically in its seat,the opening in the side of the body being provided for the introductionof the member'and the spring into said bore.

2. A door holder including in its construction a. body of a single partadapted to be secured to a support and having an interior cavity whichopens through one of its walls, a, member lying Within the cavity andbeing larger in diameter than the opening whereby to seat in saidopening and projecting through and outside the same in position toreceive'a part attached to a door,

and a spring lying in said cavity and bearing upon the member to holdit' elastically upon its seat, the body including an 0pening in one ofits side Walls through Which to introduce the said member and said.

spring.

3. A door holder including in its construction a body of a single partadapted to be secured to a support and having -an interior cavity andincluding an opening in one of its Walls communicating with the saidcavity, said body having a seat at said opening overhanging saidinterior, a ball seated in said opening and projecting ,through andoutside of the same 1n position to be engaged by a part carried by thedoor,

and a spring engaging and holding the ball elastically in its seat, thebody having an opening through one of its side Walls through which tointroduce said member and said spring.

4. A door holder including in its construc- -tion a body of a singlepart adapted to bc secured to a support and having an interior cavityand including an opening at one end communicating with. the said cavity,said body including a seat at said opening smaller in diameter than theshortest diameter` of said cavity, a ball resting upon the seat withinthe cavity and projecting partially through and outside of the openingand adapted to engage a part carried by a door, and a spring to hold theball elastically upon its seat, there being an opening in the sido wallof said part through Which to introduce the ball and the spring, thelast named opening nearest. the base of the Spring terminating outwardfrom the part of the body upon which said spring rests.

5. As an article ot manufacture, a single casting consisting; of a baseportion and a hollow portion extending therefrom, said base formino` abottom for and closing the lower end or said hollow portion, the latterhaving an opening at its other end, and fur ther provided with an,opening or window in its side connnunicating with its interior.

6. As an article of manufacture a single casting Comprising a hollowportion or shell and a base portion, the latter closing one end of theshell, a member seated within the hollowportion or shell in the open endof the same opposite the base portion, and a spring' interposed betweenthe member and the base, there being an opening or window in the side'ofsaid shell for the introduction of the member and spring.

In testimony whereof I aix my signature, in presence of two witnesses.
